TELEPHONE-HOLDER.

Specification of Letters Patent.

Application filed March 20, 1907.

Patented Dec. 15, 1908.

Serial No. 363,436.

To all whom it may concern:

Be it known that I, LOUIS S. HALLOWELL, a citizen of the United Statesof America, residing in the borough of Manhattan, in the city, county,and State of New York, have invented certain new and useful Improvementsin Telephone-Holders, of which the following is a specification.

This invention relates to adjustable telephone holders or bracketshaving the support ing arm made of two parts adapted to be moved withreference to each other on raising or lowering the holder and acounterbalancing spring to coperate with the relatively moving parts.

My invention is more especially applicable to holders or brackets inwhich the arm is tubular and the spring is contained within the tubulararm.

The main object of my invention is to so construct the supporting armthat the relatively moving parts may be maintained in frictional contactin all positions of the holder or bracket.

In the accompanying drawings Figure 1 is a longitudinal section throughthe supporting arm of the holder; Fig. 2 is a side view thereof on asmaller scale with the arm drawn down from its normal perpendicularposition; Fig. 3 is a plan view of the bracket; Fig. 4 is a crosssection on the line 44, Fig. 1, drawn to an enlarged scale; and Fig. 5is a cross section on the line 55, Fig. 1.

In my new construction of bracket, the tubular arm comprises two artsadapted to slide upon one another, and this is obtained in theconstruction here shown by longitudinally dividing the tube 8 into twoparts A and B adapted to slide upon one another and connecting themtogether at each end by means of a double-link joint comprising a link13 and an end piece 23 (24) to which one piece A or B and the link ofthe other piece are connected. Intermediate the ends the two parts areconnected together by means of pins 9 carried by one part and workingbeneath bridge pieces 10, secured b screws 12 to lugs 11 and 11 carriedby the other part. Within the tube is situated the spring which in thepresent instance is shown as a com ression spring 22, surrounding a rod14, whic projects through and is guided by a hole 15 in the lug 11 andis carried at its lower end by a bar 16. This latter in turn is carriedby and is adjustable upon a screw 17,

passing through the lug 18 and resting in a bed in the lug 19 upon thepart A. The helical spring 22 is confined between the lug 11 which iscarried by the part B, and the bar 16 which is secured to the other partA of the tube. The lower end piece 23 is swiveled to a suitable bracket20 for the attachment of the fixture to a desk, wall or other rest,while the upper end piece 24 has a socket to receive a claw 21 or othermeans to hold the telephone transmitter.

The operation of the device is as follows: After having been secured tothe desired su port by means of the bracket 20, the armstan s in itsnormal vertical position, with the telephone conveniently out of theway. On pulling the holder and telephone down for use, the transmittercarried by the end iece 24 is maintained in its vertical position by theparallel ruler-like action of the end pieces and the sliding of the artA of the annular arm over the part B, t e links 13 permitting the twoparts A and B to remain in frictional contact with each other in allpositions. The described movement of the parts A and B compresses thespring 22 since the bar 16 carried by the part A and against which thelower end of the spring abuts is thereby caused to approach the lug 11on the part B, against which the upper end of the spring abuts. Thespring tends to force the bar 16 and the lug 11 apart, and therebythrough the links 13, to return the tube to its normal verticalposition, in which it remains until again brought into use. The normaltension of the spring may be regulated of course by means of the screw17, which can move the bar 16 closer to or further away from the lug 11Another feature of the invention is thefrictional bearing of the twoportions of the arm against each other. This has a function in and ofitself since the parts are so adjusted with relation to each other thatwhen the receiver is lifted from the telephone hook, the friction issufficient to overcome in great part the tendency of the arm to fly upunder the lightened load. One of the greatest drawbacks to the old styleof support is thus over come.

I claim as my invention 1. In a device of the class described, a tubulararm comprising a plurality of parts extending the length of said arm andslidably connected together in frictional contact substantiallythroughout their length in combination with a spring actuated by themovement of said parts over one another, and means for securing said armto a convenient support, substantially as described.

2. In a device of the class described, a tubular arm comprising aplurality of parts slidably connected together and provided with a linkoint at each end, in combination with a spring actuated by the movementof said parts over one another and means for securing said arm to aconvenient support, substantially as described.

3. In a device of the class described, a supporting arm having aplurality of parts and a double-link connection between the same at eachend, in combination with a spring adapted to be actuated by the movementof said parts with relation to each other and means for securing saidarm to a convenient support.

4. In a device of the class described, a tubular arm comprising aplurality of parts slidably connected together and provided with a linkoint at each end, in combination with a spring confined within saidtubular arm, and between abutments actuated by differentparts of thetube and means for securing said arm to a convenient support,substantially as described.

5. In a device of the class described, a tu bular arm comprising aplurality of parts connected together by a link joint at each end andintermediate the ends by a pin carried by one part Working beneath abridge carried by another part, in combination with a spring actuated bythe movement of said parts over one another and means for securing saidarm to a convenient support, substantially as described.

6. In a device of the class described, a supporting arm comprising aplurality of parts extending the length of said arm and slidablyconnected together in frictional contact substantially throughout theirlength, in combination with a spring actuated by the movement of saidparts over one another, and means for securing said arm to a convenientsupport, substantially as described.

7. In a device of the class described, a supporting arm comprising twoparts slidably connected together in frictional contact, end pieces toeach of which a part is pivoted, and a link joint connection for theother part to the end piece, in combination with a spring actuated bythe movement of said parts over one another, and means for securing saidarm to a convenient support substantially as described.

In testimony whereof I have signed my name to this specification, in thepresence of two subscribing witnesses.
